An ecommerce technology stack is a set of systems with different jobs: show the store, manage orders, control stock, move parcels, publish content and report results. Names alone do not define ownership. A commerce platform can include functions that another company buys separately. The useful question is which record or system owns each decision, and how the handoffs behave when something changes.

📎 How to read this page
What it means gives the precise meaning. Operator translation gives the version you might hear in a real ecommerce meeting. In real life shows an illustrative example. Watch out and the confusion boxes show where a familiar term can mislead.
📈 Read the relationships first
These combinations are diagnostic hypotheses, not proof of causality. Compare the same period and scope, then investigate the mechanism.
System count ↑ + duplicate records ↑
Usually means: ownership boundaries may be unclear. Check next: Map the authoritative system for each field and event.
Integration count ↑ + manual reconciliation ↑
Usually means: interfaces may be missing, unreliable or poorly monitored. Check next: event timing, error handling and retry ownership.
Release frequency ↑ + production incidents ↑
Usually means: testing or rollback controls may not match the pace of change. Check next: Compare staging coverage, sandbox fidelity and uptime by customer journey.

🔀 Commerce platform vs CMS
The commerce platform owns shopping and transaction capabilities; a CMS manages content publishing. Some products combine both.
🔀 OMS vs WMS vs TMS
OMS decides how orders are routed and managed; WMS runs warehouse work; TMS plans and manages transportation.
🔀 Sandbox vs staging
A sandbox isolates development or integration tests. Staging rehearses a release in an environment intended to resemble production.
🔀 SaaS vs PaaS
SaaS delivers a finished application. PaaS supplies a managed environment for building or running applications.
